Is the cruise control still working?
sometimes it’s tied to the chip

 

No it's not working since I replaced the clock spring. Which chip are you referring to?

 

Anybody ? Please help!

 

Sounds to me you either missed a plug or bent a pin and not making contact or you installed the wrong clock spring. But all of that stuff runs down the steering column and what not. Maybe you clipped a wire when cutting old zip ties out. Or maybe left a harness unplugged

 

I opened it back up and went through it completely. Everything is hooked up. I checked the blue harness block and counted the connectors in the block and compared it to the old one and it was the same. I looked at the pins themselves and none were bent or broken. I bought the clock spring from the gm dealer. I'll send pictures tomorrow. I'm just at a loss.

The attached is specific to my 2008 model. I don't know how different, if any, it is from your truck. Test various pins to see where you should have voltage, ground, etc.

Thanks I'll look at that connector and try and figure it out.

 

have EFI Live with the DSP5 switch. It was tuned by the shop and I don't have a tuner. I did have to remove the switch but it went back together and clicks into position like it should. I'll have to look at that more closely.

Hmm do you have an aftermarket stereo in the truck or aftermarket

 

if you have aftermarket stereo pull there radio fuse and unplug everything that’s plugged into the obd2 port including the amp steps if that’s how they are getting power. I wonder if they are blocking the data line and not allowing it to establish connection to the bcm. I know the cts can do that and maybe since the truck saw it wasn’t working before and shit that part off and now since you put the new one in it cant see it. Also if you have aftermarket stereo try taking it out and plugging in the factory one if pulling the fuse didn’t work

 

I don't have an aftermarket stereo. I did splice a Bluetooth receiver into the xm wiring but that was over 3 years ago and haven't messed with it since then. The amp steps get power from the fuse block/box. They have an inline fuse. Theres a switch for the amp steps mounted on a plate under the kick panel. I can just yank the fuse one the steps and the Bluetooth receiver has an off switch. I will unplug the CTS from the obdII and see if that works. I ordered a new shift lever and I'm going to try just plugging the new one into the harness and shifting the installed one into manual and seeing if that and tow/haul work. I will try unplugging all that today and report back on the results. Thanks again!

 

Make sure your cig lighter plugs are not shorted.

 

I will check those today thanks!

 

I'm looking for your IGNO 10 amp fuse on the wiring diagram and can't find it. Wiring diagrams don't always agree with our trucks.

#8 IGN A 40A Ignition Switch RUN, START, RUN/START/ACCY, STARTER Relay

#9 IGN B 40A Ignition Switch RUN/ACC, RUN/START

Can't be one of these a/c these are 40A fuses

#27 IGN E 10A A/C COMP Relay, Park/Neutral Position (PNP) Switch, Turn Signal/Multifunction Switch, Headlamp Leveling Components, Clutch Start Switch

#37 SEO IGN 10A DEFOG Relay, Instrument Panel Cluster (IPC)

#38 TBC IGN 1 10A Body Control Module (BCM)

I will pull those fuses today thanks!!

 

it appears that that IGN0 (zero) powers your ECM and TCM. From your fuse, the power travels on the pink wire to the underhood block and then is distributed to TCM and ECM. Somewhere there is a short.

 

Thank you for the wiring diagram! Where did you find that?! I'll have Chase that pink wire from the fuse to the firewall and then into the block and then to the tcm and ecm correct?

 

It was in fact the clock spring/harness. Installed the new one and all is well.
